i know 4.10 gears dont add any HP but how much should it take off my et time on avg? i dont want a specific # like you'll run in the 14's or anything like that, but i mean like 1 sec, 1/2 sec? anything like that would be great. and im going 4.10 bc i'll be staying N/A for like...... 7-8 years. thanks in advance

With sticky tires and good traction, I dropped .4 from just swapping from 3.27's to 4.10's

I've heard .5 seconds on average. And bullitt, you just ran it once or twice? I'm sure you could knock off more with some practice.

I've run my car over 100 times down the track, more than half with the 4.10's. I just don't have enough horsepower to really pick up any more than .4, I was at the best times I could possibly run with 256rwhp on a full weight car. I already had great traction and decent 60ft times before the 4.10's, so I was expecting about a .3 gain, but I can live with .4.....:shigrin

Around 2200rpms at 70mph isn't so high. My old daily driver turned over that and it was an unmodded Nissan Hardbody pickup.

Yeah, 2200 at 70 doesn't sound bad at all. I just ordered my 3.73's, so too late for changes. :laugh:

60mph=2000rpm
